# OSCILLATION .. kaon antikaon

what's the relation between kaon antikaon oscillation and two body problem
. My teacher told me that I should learn kaon antikaon oscillation. . I can't find anything about it.

two body problem?

under
What education level are you doing this in?
What did you try? Wikipedia? College library books?
https://en.wikipedia.org/wiki/Kaon#Oscillation
undergraduate level... infact I can't understand properly where should I look for

Kaon-Antikaon oscillation doesn't mean that you have them two going around each other, that's why I don't see any relation with the 2-body problem you mentioned.
In Kaon-Antikaon oscillations you have a Kaon transforming to Antikaon ($K^0 \rightarrow \bar{K}^0$).

I can't understand properly where should I look for
I guess the wikipedia can give you some information. From then on, you can google search or ask.

Kaon-Antikoan oscillation is often used as an example of a real-world two-state system.

how?

You have two states, and transitions between them if your chosen basis are not the mass eigenstates.

The neutral kaon may be a particle or an antiparticle... whether it is a particle or an antiparticle may be considered a state of the system consisting of a single neutral kaon. It's something you can measure.

In QM terms, you can imagine an operator that measures the particle-antiparticle state of the neutral kaon ... the trouble with any of us going further is that "finding out about the neutral kaon oscillations" is the task you have been set. If we just tell you, that would amount to "doing your homework for you" which would defeat the purpose of assigning you the work in the first place. There is a great benefit to you in learning to carry out this sort of research without knowing initially where to start or what you will discover. Indeed: only if you are willing to search into the unknown can you be a scientist. Go for it!

Sorry; I interpreted the "two-state system" as "two-body system" (in connection to my previous answer/post).
